WHEELTOP EDS TX Disc Brake Carbon — Full Groupset Bundle
Everything you need to build a complete electronic drivetrain in one box — no separate crankset order, no cross-referencing a chain compatibility chart, no mismatched brake calipers. This bundle pairs the WHEELTOP EDS TX wireless electronic shifting kit (carbon fiber disc brake levers, hydraulic calipers, front + rear derailleur with the Carbon Fiber Hollow Oversized Pulley Cage) with a RACEWORK GRS-RK2 aluminum alloy double crankset, a 12-speed SUNSHINE-SZ cassette, and a SUMC SX12 chain. Pick your chainring ratio and cassette range below, and the rest of the drivetrain is matched and ready to install.

A Verified Combination, Not Just Parts in a Box
This isn't a random parts bundle — Aoeagle built this exact combination onto a complete bike and put it through rigorous testing to confirm smooth, precise shifting between these components and the WHEELTOP EDS TX before offering it as a set.
EDS TX Electronic Rear Derailleur, Oversized Pulley Cage Standard
Driven by a built-in 800mAh rechargeable battery at 8.4V, the EDS TX rear derailleur shifts instantly on a button press — zero cable lag, zero stretch over time. It ships already configured to 12-speed, dialed in for the SUNSHINE-SZ cassette included in this bundle. Unlike the standard TX, this build comes with the carbon fiber hollow oversized pulley wheels fitted from the factory — not an optional add-on. Charges through a magnetic Pogopin connector — snap it on, no port covers, no corrosion.
Lower Friction, Standard on This Bundle
Oversized pulley wheels reduce the chain's wrap angle around each pulley, which means less chain articulation per revolution and measurably lower friction across the full drivetrain — noticeably smoother under hard pedaling effort, with no learning curve and no setup difference from a standard TX rear derailleur.
Why Oversized? The Chain Wrap Angle Difference.
At 12 teeth, the oversized pulleys are physically larger than a conventional jockey wheel — letting the chain bend through a gentler arc at each engagement. Less arc per revolution means less per-link articulation friction across every pedal stroke. The hollow carbon fiber construction removes mass from the pulley body without sacrificing torsional stiffness, keeping the drivetrain quieter and more responsive under load.

Electronic Front Derailleur — Complete 2× Groupset
Every bundle ships with both the front derailleur and rear derailleur, matched to the RACEWORK double chainring crankset below — a complete 2× drivetrain, ready to install.
Precise Front Shifting on Demand
The EDS TX front derailleur runs on its own built-in 600mAh rechargeable battery and shares the same 8.4V system, magnetic Pogopin charging, and BLE/ANT+ wireless link as the rear unit. Pair both derailleurs to the WHEELTOP app for synchronized setup, gear mapping, and live status — front and rear shift in concert with a single button press from the lever.

Cockpit & Disc Brake Configuration
Disc Brake — Carbon Fiber Lever
The EDS TX Disc Brake build pairs a carbon fiber lever body with a matched pair of hydraulic disc brake calipers — electronic shifting precision, full ceramic pistons, zero cable clutter.
Shift with a Button. Brake with the Lever.
A press of the shift button sends the command wirelessly straight to the derailleur — no cable pull, no mechanical play to wear in. Each lever runs on a single CR2032 button battery, swappable in seconds without tools. The carbon fiber lever body is high-grade cold-laminated carbon fiber, actuating the hydraulic disc calipers included in this bundle.

Carbon Fiber Body — Light, Stiff, Precise.
The carbon fiber lever body is high-grade cold-laminated carbon fiber. The woven surface texture holds grip through wet descents without repositioning. The shift button sits exactly at thumb reach: index finger pulls the brake lever, thumb taps the shift button — no hand movement required.
One Lever, Two Functions.
Brake and shift from the same contact point. The lever body handles the brake pull, the button handles the gear command — both without taking your fingers off the bar.

CNC Unibody. Built to Run Cool.
The caliper body is CNC-machined from aluminum alloy as a single unit, ensuring rigidity and long-term safety under hard braking. Shark-fin heat sinks on the caliper body increase surface area for better heat dissipation, slowing down thermal fade on long descents. A unidirectional oil circuit prevents brake fluid from flowing backward, keeping lever feel sharp and response quick.
Full Ceramic Pistons
Full ceramic pistons resist high heat and hold a consistent bite point ride after ride — no fade, no spongy lever after a long climb or fast descent.
Flat or Post Mount. Pre-Bled. Ready to Ride.
Hoses are pre-cut and pre-bled from the factory. Unbox, install, ride. The mineral oil system is non-corrosive and easy to maintain at home. Confirm your frame and fork's caliper mount type (flat or post) and rotor size before ordering.
A 6061 aluminum crank arm paired with CNC-machined 7075 aluminum chainrings — matched to the EDS TX front derailleur above and ready to bolt straight onto a threaded bottom bracket shell.
Matte Black 6061 Crank Arms. Real 7075 Alloy Rings.
The GRS-RK2 crank arm is 6061 aluminum construction at 170mm — no length options, so it's a straightforward fit for the vast majority of road frames. The chainrings are CNC-cut from 7075 aluminum, the same grade used in premium aftermarket rings, for consistent shifting under load and long-term wear resistance, and mount to the spider on a 3-bolt direct-mount pattern rather than a traditional 4/5-bolt BCD. A 24mm straight spindle threads into a BB51-standard bottom bracket, finished in matte black throughout.

Need a DUB Spindle Instead?
This crankset is also available in a DUB spindle version. If your frame or bottom bracket needs DUB instead of the standard 24mm spindle, leave us a note at checkout and we'll arrange it.
Quick Shift Design
The chainring pair is CNC-machined from a single piece of 7075 aluminum for a one-piece integrated construction — high strength and lightweight, without the flex of two separately bolted rings. The precision-cut tooth profile is shaped to guide the chain between rings faster and more predictably, for significantly improved shifting efficiency.
Compact
50-34T
The easier-spinning ratio — noticeably more manageable on long climbs and rolling terrain. The natural pick for most road and gravel riders, and for anyone pairing with the wider 11-34T cassette option below.
Mid-Compact
52-36T
A taller top end for faster group rides and flatter routes, while the 36T inner ring still leaves a manageable gear for moderate climbs. Best suited to stronger riders or those on rolling-to-flat terrain.
Hollow-Milled Crank Arm Design
Forged and CNC-machined, the crank arm is cut away in a hollow rib pattern along its length — lighter in weight, with higher strength and power-transfer stiffness than a solid arm.
660g for the Complete 50-34T Crankset
The 170mm 6061 aluminum crank arms and 7075 aluminum 50-34T chainrings come in at 660g together (bottom bracket not included) — a straightforward, budget-friendly alternative to the carbon fiber version of this crankset.
BB51 Threaded Bottom Bracket, Cups Included
The crankset ships with its matching BB51 threaded bottom bracket cups — no need to source one separately. BB51 covers both 68mm and 73mm threaded shell widths, so it fits most standard road and MTB threaded frames. Threading straight into a standard threaded shell also sidesteps the creaking that press-fit bottom brackets are notorious for.
Is Your Frame Compatible?
As long as your frame's bottom bracket shell is BSA (English thread) — the most common standard — this bottom bracket installs without any issue.

SUNSHINE-SZ 12-Speed Cassette — Three Range Options
Precision-cut 12-speed cogs on a standard Shimano HG-compatible driver — pick the range that matches your terrain and set the EDS TX to 12-speed in the WHEELTOP app to match.
This Cassette Uses Shimano HG Freehub Bodies
SRAM XD
SHIMANO HG
HG Driver Only — Not XD/XDR Compatible
This cassette installs on a standard Shimano HG-splined freehub body. It does not fit a SRAM XD or XDR driver. Confirm your rear hub's freehub body before ordering.
Each cog is precision-machined for clean, quiet engagement, and the whole cassette is a straightforward drop-in for a standard Shimano HG freehub body — the same driver used for 11-speed cassettes, no special driver needed. Because the EDS TX sets its speed count entirely in the app rather than through a fixed cable-pull ratio, it indexes cleanly against whichever range you choose below.
Close Ratio
11-28T
11-12-13-14-15-16-17-19-21-23-25-28T · 306g
Tight steps between gears for flat-to-rolling roads where you want to hold a precise cadence. Pairs naturally with the 52-36T chainring.
All-Rounder
11-32T
11-12-13-14-15-17-19-21-23-25-28-32T · 367g
The middle-ground range — enough spread for mixed terrain and moderate climbs without giving up too much at the close end. A safe default for most riders.
Wide Range
11-34T
11-12-13-15-17-19-21-23-25-28-31-34T · 388g
A genuine bail-out gear for hillier routes or riders who'd rather spin than grind. Pairs well with the 50-34T chainring for a climb-friendly setup.
Complete Groupset Bundle
SUMC SX12 Chain — 12-Speed
Sized and speed-matched to the cassette above, so there's no separate chain compatibility chart to cross-reference.
SUMC SX12 — 126-Link 12-Speed Chain
A dedicated 12-speed chain built with SUMC's double-X outer plate profile for smoother shifts under load and a slight friction reduction over a generic chain. Supplied at 126 links (standard length, trim to fit your frame during installation) and finished in silver to match the rest of the drivetrain hardware.
